'Biopolitics' is a much-used concept in recent academic literature. One of its main fields of application is in the analysis of public health projects. This article analyses the national Explicit Health Guarantees project in Chile from that perspective. However, we criticize the standard invocation of 'biopolitics' by observing that such public health projects require technoscientific operations that establish truths and regimes of obligation for the groups involved -understanding regime both as a set of imposed orders and a set of regulated processes. Specifically, the Explicit Health Guarantees project defines what we call 'speculative objects'. These have two characteristics: (a) They relate highly diverse entities into integrated wholes that are and involve objects of knowledge and uncertainty, and (b) this integration creates regimes of obligation considered as scientific truths on many different groups. We conclude by proposing new questions about the notion of biopolitics and its relationship with uncertainty and speculation.

智利卫生项目中的生命政治和投机对象。

“生命政治”是最近学术文献中经常使用的概念。它的主要应用领域之一是公共卫生项目的分析。本文从这个角度分析了智利的国家明确健康保障项目。然而，我们通过观察此类公共卫生项目需要技术科学操作来批评“生命政治”的标准调用，这些操作为所涉及的群体建立真相和义务制度——将制度理解为一组强加的命令和一组受监管的过程。具体来说，Explicit Health Guarantees 项目定义了我们所说的“推测对象”。它们具有两个特征：(a) 它们将高度多样化的实体联系成综合的整体，这些整体是并涉及知识和不确定性的对象，(b) 这种整合创造了被视为许多不同群体的科学真理的义务制度。最后，我们提出了关于生命政治概念及其与不确定性和推测的关系的新问题。
